Hi folks, My shorewall dump file is attached. I''m trying to set up the network so that the following happens: HDLC0 - external address (203.117.160.170) | Shorewall host: BACCHUS | eth0 - internal address (192.168.21.1) | internal network ------ | | other machines | 192.168.21.3 (203.117.137.34) I have the settings in nat, but I just cannot ping 203.117.137.34 from a host outside. I''ve verified that I can ping 192.168.21.3 from BACCHUS. Appreciate any help Cheers Lim Swee Tat
